Ordering number : E*NA0633A Bi-CMOS LSI LV25400W For Automotive Applications DSP Tuner Front End Overview The LV25400W is a tuner front end IC that supports the Sanyo SDRS400 car radio DSP. The LV25400W supports worldwide radio standards including the FM bands used in US, Europe, and Japan as well as the LW, MW, SW, and FM weather bands. It adopts an image canceling mixer for the FM mixer and incorporates a fast PLL locking function to support RDS. The LV25400W also supports automatic alignment using CCB bus control. It requires external EEPROM. The LV25400W can implement a DSP tuner at low cost with a minimal number of external components.

FM mode (AM/FM = 0) A filter is formed on pins 8 and 11. Since this filter can be independent of the filter used in AM mode, PLL locking can be fast. AM mode (AM/FM = 1) A filter is formed on pins 9 and 10 and with the two internal switches SW1 and SW2. An additional filter is added using an internal resistor and an external capacitor. W-filter mode (MODE = 1) Both filters are enabled, regardless of the AM/FM bit. (All of pins 8, 9, 10, and 11, and switches SW1 and SW2 are used.) This is used when sidebands occur in AM mode, and in other cases. However, there are case where, depending on the particular filter component values, this mode cannot be used.

No.A0633-36/42 LV25400W Phase Comparator and Charge Pump Circuits (1) Phase comparator and charge pump operation In the PLL circuit block shown in figure 1, the phase comparator compares the phases of the reference frequency (fr) and the comparison frequency (fp), and outputs the amount of the phase difference from the charge pump. Figure 1 PLL Circuit Block RF Mixer Leakage during strong-field input fr Reference Divider Phase Detector Programmable Divider Charge Pump LPF VCO fp Figure 2 shows the phase comparator/charge pump output characteristics. The phase comparator outputs a voltage Vφ that is proportional to the phase difference φ between fr and fp. The phase comparator's characteristics can be switched by changing the phase comparator dead zone mode setting. The phase comparator can be set to modes (DZA, DZB) in which both the charge pump p-channel and n-channel sides are turned on when the phase difference is small, or can be set to a mode (DZD) that does not output the phase difference when the phase difference is small. Figure 2 Phase Comparator/Charge Pump Characteristics Vφ[V] Vφ[V] fp > fr D ZA mode fp > fr D ZB mode φ err[ns] fr > fp Dead Zone(--) φ err[ns] Vφ[V] D ZC mode Dead Zone(-) fr > fp Vφ[V] fp > fr D ZD mode φ err[ns] fp > fr φ err[ns] fr > fp Dead Zone ≈ 0 fr > fp Dead Zone(+) No.A0633-37/42 LV25400W (2) Dead zone mode characteristics The table below presents an overview of the characteristics in each of the dead zone modes. Setting Dead zone mode Charge pump (p/n-channel) state at 0 phase Dead zone width (for difference reference purposes) DZ1 DZ0 0 0 DZA On/on - -(-15[ns]) 0 1 DZB On/on - (-8[ns]) 1 0 DZC On or off 1 1 DZD Off/off Close to 0 (0[ns]) Notes Illegal setting + (+8[ns]) (3) Dead zone mode characteristics and selection criteria This section describes the characteristics of each dead zone mode and the criteria for selecting that mode. (1) DZA mode In DZA mode, the correction signal is output from the charge pump even if the reference frequency (fr) and comparison frequency (fp) match. This results in excellent signal-to-noise ratio characteristics. However, due to the generation of reference frequency component sidebands, beating may occur in the presence of a strong input signal. This is because the PLL loop responds sensitively to leakage components from the RF stage through the mixer and this modulates the VCO. (2) DZB mode Like DZA mode, in DZB mode the correction signal is output from the charge pump even if the reference frequency (fr) and comparison frequency (fp) match. However, the correction signal voltage is lower in DZB mode than in DZA mode. The feature of this mode is that it provides a better signal-to-noise ratio than DZC or DZD mode yet is less susceptible to beating than DZA mode. (3) DZC mode In DZC mode, a correction signal proportional to the phase difference between the reference frequency (fr) and comparison frequency (fp) is output from the charge pump. A small amount of noise may occur when the phase difference is close to 0 ns. Since the signal-to-noise ratio may degrade significantly at low temperatures (under -30°C), this mode should not be used. (4) DZD mode In DZD mode, a correction signal proportional to the phase difference between the reference frequency (fr) and comparison frequency (fp) is output from the charge pump. The correction signal is not output when the phase difference is in the vicinity of ± <a few ns>. As a result the signal-to-noise ratio is worse than the other modes, but the occurrence of beating is suppressed. No.A0633-38/42 LV25400W LV25400W bit control specification: reference values 1.
